Shouldn't museum conservators be paid like museum fund raisers?

I recently received a fund raising pitch from the Museum of Modern Art which offered me a chance to win lunch and a look behind the scenes of the museum — a visit to the storage rooms full of extraordinary works, a state-of-the art conservation lab where artworks are treated, and the imaging studio where artworks are photographed–  if I donated at least $25 before the end of 2013.  It made me wonder why, if at least this museum views its conservation department as  valuable for fundraising, aren’t museum conservators paid at anywhere near the same level as fundraisers.
